Detailed Description

template<typename Mutex>
struct MutexDebug< Mutex >::Context

For passing context to SyncDebug.

Constructor & Destructor Documentation

Context() [1/2]

template<typename Mutex >

MutexDebug< Mutex >::Context::Context ( )

inline

Constructor.

Context() [2/2]

template<typename Mutex >

MutexDebug< Mutex >::Context::Context ( latch_id_t  id )

inline

Create the context for SyncDebug.

Parameters

[in]

id

ID of the latch to track

Member Function Documentation

locked()

template<typename Mutex >

void MutexDebug< Mutex >::Context::locked ( const Mutex *  mutex, const char *  filename, ulint  line  )

inline

Set to locked state.

Parameters

[in]	mutex	The mutex to acquire
[in]	filename	File name from where to acquire
[in]	line	Line number in filename

locked_from()

template<typename Mutex >

virtual std::string MutexDebug< Mutex >::Context::locked_from ( ) const

inlineoverridevirtual

Returns

the name of the file and line number in the file from where the mutex was acquired "filename:line"

Implements latch_t.

release()

template<typename Mutex >

void MutexDebug< Mutex >::Context::release ( )

inline

Reset to unlock state.

to_string()

template<typename Mutex >

std::string MutexDebug< Mutex >::Context::to_string ( ) const

inlineoverridevirtual

Print information about the latch.

Returns

the string representation

Implements latch_t.

Member Data Documentation

m_filename

template<typename Mutex >

const char* MutexDebug< Mutex >::Context::m_filename

Filename from where enter was called.

m_line

template<typename Mutex >

ulint MutexDebug< Mutex >::Context::m_line

Line number in filename.

m_mutex

template<typename Mutex >

const Mutex* MutexDebug< Mutex >::Context::m_mutex

Mutex to check for lock order violation.

m_thread_id

template<typename Mutex >

std::thread::id MutexDebug< Mutex >::Context::m_thread_id

Thread ID of the thread that own(ed) the mutex.
